Effects of applying sheep manure on soil properties of kyoho vineyard
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 12
Abstract
"In order to improve the soil fertility of vineyard by rational application of sheep manure, and reduce the pollution of nitrogen, iron, copper and other substances in sheep manure to the environment, with fully decomposed sheep manure as the base fertilizer, the experiment, taking the soil without base fertilizer as the control check (CK), was set up by applying 20, 40, 60, 80 and 100 t/hm2 of base fertilizer respectively to study the influence of the sheep manure returing on the moisture, pH and as well as total nitrogen, available phosphorus and available potassium contents in the soil. The results showed that sheep manure returning could improve soil moisture, and the deep soil water storage capacity increased with the increment of fertilization amount. pH value of the soil decreased under sheep manure returning mode, while contents of total nitrogen, available phosphorus and available potassium in different layer were increased with the increment of fertilizing amount. Furthermore, sheep manure returning can improve the content of organic matter in the soil, which was increased in different soil layers with the increase of fertilizing amount. The cation exchange capacity (CEC) in each soil layer reached the maximum value (15.62, 14.70 and 12.25 cmol/kg respectively) when 100 t/hm2 of sheep manure was applied."
